<p>Various techniques for enhanced support of stream adaptation and splicing based on clean random access (CRA) pictures are described. Instead of using a flag in the slice header to indicate that a broken link picture is present, a distinct network abstraction layer (NAL) unit type can be used to indicate the presence of a broken link picture. In some implementations, a first distinct NAL unit type may be used to indicate the presence of a broken link picture with leading pictures, while a second distinct NAL unit type indicates the presence of a broken link picture without leading pictures. In some implementations, a third distinct NAL unit type may be used to indicate the presence of a broken link picture with decodable leading pictures.</p> |
